Diver-led visual surveys at 11 mesophotic reef sites around Bermuda found that high densities of lionfish were associated with both higher abundances of prey fish and higher prey fish biomass. However, the influence of seawater temperature was found to have the strongest effect on lionfish distribution, with higher lionfish densities recorded at sites with lower bottom temperatures. These results suggest that cold-water upwelling may result in higher abundances of prey fish and lionfish.

Brazilian researchers arrived at this conclusion after conducting cardiovascular fitness tests with boys and girls aged 10-17. The results were published in Cardiology in the Young.

The study shows the advantages of herbicide spraying and intensive fertilization in reforestation programs to mitigate the effects of climate change.

Brazilian researchers develop a program for high-performance computers to map specific portions of plant DNA faster and less expensively for use in breeding more productive and stress-resistant varieties.

In another major clinical breakthrough of the Walk Again Project, a non-profit international consortium aimed at developing new neuro-rehabilitation protocols, technologies and therapies for spinal cord injury, two patients with paraplegia regained the ability to walk with minimal assistance, through the employment of a fully non-invasive brain-machine interface that does not require the use of any invasive spinal cord surgical procedure. The results of this study appeared on the May 1, 2019 issue of the journal Scientific Reports.

A study by Brazilian researchers in partnership with Harvard estimates the impact of five risk factors on the incidence of cancer- physical inactivity, unhealthy diet, overweight, smoking and alcohol consumption.

Animals in hard-to-reach places, especially strange, 'unattractive,' animals, may completely escape our attention. We don't know what their role is in the environment. In fact, we don't even know they exist. New research may double the number of species of a little-known marine creature, based on DNA studies of its larvae.
